Definitely FF/FH, but probably not UK built. The extra vents in the front panel suggest it was built locally in Australia, ands that probably means a completely different model name to those used in the UK.

Australian built trucks had extra air vents in the upper grille each side of the name plate. These were put in locally and may indicate a Diesel engine but at the end of the day they constitute a "Tropical" cooling mod.

Grille is missing but possibly heavier 7.20, 7.50 or 7.60 (7-Ton or 8-Ton in UK versions) as no evidence of horizontal bar fixings.
